7-Keto is a safe metabolite of Dehydroepiandrosterone (DHEA). It is produced naturally by the adrenal glands, but levels of 7-Keto decline significantly with age. 7-Keto stimulates the thyroid, which controls thermogenesis, or fat burning. Specifically, 7-Keto boosts the production of T3 thyroid hormone, which has the greatest effect on the body's metabolic rate. It is needed to help the body lower its fat storage set point, which governs the body's efforts to maintain ideal weight. The body works to meet this fat set point daily. If you want to keep weight off, 7-Keto becomes a prized nutrient. 7-Keto also helps prevent muscle atrophy and boosts immune function.
